Hi every one im super noobies in android..please help me

hi sir this is my scenario..

i install a nxt5 to my u20i using recovery mode then suddenly it goes to bootloop

then i restart my phone to restore my stock rom but i can not enter in recovery mode

that's why i flash my phone using SEUS,PC companion and Flashtool i succeed in flashing using those three tools but icannot enter in recovery mode.it boot normally..i didnt try to unlock my bootloader...

i search the whole day to repair my recovery but i failed..sorry for my english..

please help me..
[Sony Ericsson XPERIA X10 Mini] SmG67:
Ok :) You have the stock rom now.. so you can install recovery the way you did it before... (you know, go through the rooting process again and so on)

The ROM you tried to flash depends on a custom kernel, and the custom kernels have recovery built in, so it's not included in the ROM, that's why you lost it.

If you don't (want to) use a custom kernel, you need to find a ROM that is built for the stock kernel. Those ROMS will have the recovery included.

So in short: ROM for stock SonyEricsson kernel will have recovery included.

ROM for custom kernel will not have recovery, because it's in the kernel itself.
[Sony Ericsson XPERIA X10 Mini] azurada17:
sir i did not flash my kernel..it just my rom..

sir sorry for being noobies..

is kernel is bootloader?
[Sony Ericsson XPERIA X10 Mini] SmG67:
Yes, i know you did not flash a kernel. I tried to explain why you lost your recovery.

Think of your phone as a computer:

The hardware by itself can't do anything, so it needs software.

On a computer, you have a bios, or uefi, that initialises some hardware parts and then tries to find an operating system. On your phone it's called the bootloader.

The bootloader looks for the kernel, and loads it when it finds one.

The kernel then looks for the userspace software.On your computer it loads Windows, or Linux or whatever you have on there. On the phone that's called the ROM.

The bootloader on the phone is locked to look for the stock Sony Ericsson kernel, anything else will not work. But you can unlock the bootloader so it can find other kernels too.

The SonyEricsson kernel does not have recovery built in, so when you put recovery on your phone, it's installed in the ROM.

When you flash another ROM it gets overwritten, so if the new ROM does not have recovery included you will lose it.

A custom ROM that runs on Stock Kernel will have recovery included.

A custom ROM that runs on a custom Kernel will NOT have recovery included, because it is built into that custom Kernel.

So when you flash that ROM you will lose recovery.

So you went back to the original firmware, you will need to root the phone again and install recovery again, and then flash a ROM that says it will run on the Stock kernel.

The Nxt5 ROM expects recovery to be in the kernel, so it's not suitable for the SonyEricsson kernel.

I hope you understand this :)
[Sony Ericsson XPERIA X10 Mini] azurada17:
Thank you for your reply sir...

can i ask again...

how can i install recovery...

i tried the xrecovery,cwm, zhidzu using root xplorer but it did not work..

can you give me some links or tutorials..

and about the bootloader sir i tried to unlock it but flashtool say that bootloader:unrootable..

my date code is 10w44

can you help me sorry for bothering you sir.. :):)

I want to be safe before I switch to anything from CM10.1
[Nook HD, HD+ Q&A, Help & Troubleshooting] riboswitch:

[Nook HD, HD+ Q&A, Help & Troubleshooting] oboefiend:
It says I'm good! Thanks!
[Nook HD, HD+ Q&A, Help & Troubleshooting] riboswitch:
you are welcome my friend :)
[Nook HD, HD+ Q&A, Help & Troubleshooting] LEECH666:
I was under the impression that the emmc check app from the play store was only meant for finding out the type of NAND device inside your Nook. IIRC, The actual sanity check performed by it is for a different (older) type of emmc brick bug and not the current TRIM related brick that could be observed in some CM 10.2 builds, which had TRIM enabled. So I wouldn't conclude yet, that your device is safe ... Better cross check the NAND type with the CM wiki article. (Sorry I don't have the link at hand. Just google it.)
[Nook HD, HD+ Q&A, Help & Troubleshooting] Jann F:
The eMMC that has the bug is named MAG2GA.

I have this one too, but I'm running the TRIMfix Kernel for testing.
[Nook HD, HD+ Q&A, Help & Troubleshooting] oboefiend:
eMMC chip:

Type: SEM32G

Date: 11/2012

CID (huge number)

FwRev: 0x90

Does this mean it's ok?
[Nook HD, HD+ Q&A, Help & Troubleshooting] HiddenG:
Yes, it's perfectly fine for you to run CM10.2 with no problems. Your device does not have the chip with the issue.

Your chip is: SEM32G, not MAG2GA. The MAG2GA chip is the one specifically with the issue.

All the best. ;)
[Nook HD, HD+ Q&A, Help & Troubleshooting] mogators1:
Just got my refurbished Nook HD+. Does it have to be rooted to get the correct information? I have made a backup of my stock and installed the emmc check from the Play store and it is saying I have the affected chip. This was done while running stock.

So if I have the affected chip, what exactly does that mean? I was planing on running CM 10.1.3 on it which I think is not affected. Will my device get slow as the memory fills up?
[Nook HD, HD+ Q&A, Help & Troubleshooting] HiddenG:
If you're going to run CM 10.1.3-stable, you're good to go. You don't have to worry about anything.

If however, you're planning to install CM 10.2 or decide to upgrade to it; you may have issues with the performance being degraded, as CM 10.2 is based on Android 4.3; and 4.3 introduced a new way of managing storage, using something called TRIM in attempt to increase performance.

If you upgrade to CM 10.2, and then revert back to Stock ROM, or CM 10.1.3 (or any other ROM), you will still notice the issues; as your hardware has been affected. If you try to install the TRIM kernel, that could also brick your device.

I'd only install CyanogenMod 10.1.3 (stable) and stick to it. Perhaps in the future we could solve this EMMC TRIM hardware issue; as the 2012 Nexus 7 uses the same chip, and it's been patched via a software update. In the future, perhaps we could port that patch onto the Nook.

Again, for now CM 10.1.3 is your best route.

All the best. ;)
[Nook HD, HD+ Q&A, Help & Troubleshooting] leapinlar:
Even if you run CM10.1.3, you can still get lag, which is what TRIM is supposed to fix (TRIM is a repair utility, not a new way of storage). It makes no difference which you run, CM10.1.3 or CM10.2, it is possible to get lag. The difference between the two is CM10.2 has the TRIM utility built in and CM10.1.3 does not.

That said, I run CM10.1.3 and have never experienced lag. But I have a SEM32G chip too (not an buggy chip). However, many users have reported lag on CM10.1.3. Since TRIM is not built in, they run the TRIM app from the Play Store. And if they have the affected chip, some have reported a brick.
[Nook HD, HD+ Q&A, Help & Troubleshooting] plissk3n:
Hello guys,

I just discovered this thread and it seems that I got a bad chip (MAG2GA). Unfortunatly I installed CM 10.2 (20131106-NIGHTLY) the day I got the tablet (last week). So far I am pretty happy with the tablet but sometimes some apps are crashing. Most of the time it is chrome but not exlusivly.

Should I go back to 10.1 because of the memory chip i got? Should I send the tablet back and ask for a different device? This could be costly because I ordered in the USA but live in Germany.

Will future updates fix the problems? I planed to use the tablet at least for two years and so future updates should be possible for my tablet.

Thanks for your responses, best whishes.
[Nook HD, HD+ Q&A, Help & Troubleshooting] faehsemc:
So my chip is the supposed bad one. I am on liquid 4.3 and honestly it runs better than it did stock. I don't have any random errors or anything. Should I not be on any 4.3 ROM even though it says my chip is sane?

I just got my Nook HD+ from BN Yesterday

Supposedly brand new but with a MAG2GA chip. Should I be angry? If it has that chip is actually a refurb being sold as new?
[Nook HD, HD+ Q&A, Help & Troubleshooting] leapinlar:
No, they have stacks of these things they are trying to get rid of. They over ordered months ago and are trying to reduce inventory to improve their financial position. That's why the lowered prices. I don't think they are making any new ones.

[Nook HD, HD+ Q&A, Help & Troubleshooting] FoxForceFive:
The brickbug app is not checking for the mag2ga chip as being faulty as that's not what it was designed for.
[Nook HD, HD+ Q&A, Help & Troubleshooting] chili81:
What if you have the bad chip?

If you do have the affected chip, any predictions on what the future looks like? Are these the only rays of hope:

1) Someone ports the Nexus 7 patch to 10.2

2) Google integrates the patch logic into android core 4.4 so CM11 might be safe on Nooks?

It sounds like stock nook OS is based on 4.0.3... so doesn't sound like B&N is too hungry to push the stock OS past this barrier.
[Nook HD, HD+ Q&A, Help & Troubleshooting] FoxForceFive:
The patch is a kernel patch, still in testing, but the trim only works on a particular cm10.2 fw.

The details are in the trim thread.

It's still not regarded as 100% safe cos it's not been tested enough.

Whats is B & N's policy, if any, regarding returning those with faulty chips under warranty?
[Nook HD, HD+ Q&A, Help & Troubleshooting] FoxForceFive:
If the faulty emmc chip leads to a brick it simply won't boot at all, so they won't know why it happened & will honour it if under warranty.
[Nook HD, HD+ Q&A, Help & Troubleshooting] whatagonad:
Thanks but I was more thinking about an official policy from B & N for working tablets that are inherently faulty...can only assume they dont have such a policy and don't care......Also I was thinking of returning mine to the retailer I bought it from (bought from John Lewis in UK who have a good return policy generally) - I'm sure a bricked unbootable tablet would be easier to return but it would be nice to not have to do that!
[Nook HD, HD+ Q&A, Help & Troubleshooting] FoxForceFive:
It shouldn't be an issue at all.

There's a stock recovery image in here & a stock rom also, so you can simply reflash those & return it.

John Lewis (I'm in the UK too) will barely look at it, they really are fantastic with returns.

[Nook HD, HD+ Q&A, Help & Troubleshooting] Jann F:
As far as I know it will brick on the SECURE ERASE commend within the TRIM function, but I think it's still unknown whether only fw rev 0x05 or both 0x05 and 0x06 are affected.

e.g. Google Nexus devices with the same chip had got kernel patch for it.

I got a MAG2GA FW rev. 0x06 module and am running the TRIM Kernel for the last 3 weeks without any problems.
[Nook HD, HD+ Q&A, Help & Troubleshooting] Nolfer:
Hey everyone, I'm new at posting, but I followed this forum for a long time and had experience flashing an xperia arc s, and now my nook hd+.

I thought I might share my experience with you to provide some feedback on the emmc bug.

I bought a:

°refurbished Nook HD+ 32GB from the USA

°Flashed the 10.1.3 STABLE

°eMMC Brickbug Check (from google app store): MBG4GA

°FwRev: 0x06

°All was ok, but laggy sometimes

So, knowing that my chip should be unaffected by the bug, I went ahead and tried the cm-10.2-20131123-NIGHTLY-ovation.zip, installed cwm and gapps as always, and installed the trimfix kernel ovation 2.zip from sdcard, to try and get a better responsive system.

Ran the "fstrim -v /system, data and cache" commands and got the "n bytes trimmed" messages.

Ran vdc fstrim dotrim, got "200 0 0" message.

It's been a couple hours and everything is fine, seems to be more fluid.

I will keep you guys updated just in case anything goes wrong

[Nook HD, HD+ Q&A, Help & Troubleshooting] soycory:
OK... So, I'm a real noob. I have a new (refurbished) Nook HD+ 32gb with MBG4GA rev 0x06. My questions:

1. I do not have the Trim issue with my ram (Probably). Does this mean that If I put Cyanogenmod 10.1 my performance will gradually degrade due to not having Trim? If I use a new ROM with Trim I may (not likely) brick the internal memory?

2. To make sure I understand... If I brick my ram with the rom I can create an SD rom that will run only of the micro SD card that should function like a normal ROM?
[Nook HD, HD+ Q&A, Help & Troubleshooting] TheApocalyptican:

[Nook HD, HD+ Q&A, Help & Troubleshooting] manchester-hi:
Just to confirm, if I have the Nook HD (Hummingbird) without the faulty MAG2GA, do I still need to flash the TRIM kernel when flashing the CM 10.2, CWM and gapps zip files?

I ask because per wiki.cyanogenmod.org/w/EMMC_Bugs, it suggests that only the Nook HD+ Ovation is affected - hence I was wondering therefore whether the ROMM for the Nook HD (hummingbird) would have the TRIM kernel already enabled?

Thanks!
[Nook HD, HD+ Q&A, Help & Troubleshooting] josim:
Jann F,

I have the same module as you. Do you have anything new to report? Are you still using TRIM? Is all OK with you Nook?

I'm running CM 10.1.3 and had lag. Leapinlar suggested in another thread to format 'data and mediadata' thru CWM. I did this and it fixed my lag however, I had to re-register with CM, and allow play store to reinstall some apps and manually reinstall other apps w/Apps Back-up and Restore. While i am happy with the results, this is not something i wish to do on a regular basis.

So, do you recommend using TRIM while staying away from the SECURE ERASE command?

Thanks,

josim

Hi there, noticed that you have the same eMMC as me, was wondering if anything new has been found or if you have had any issues? Am still on 10.1.3 CM but am feeling the some lag now so tempted to upgrade to the latest 10.2.... Thanks
[Nook HD, HD+ Q&A, Help & Troubleshooting] Nolfer:
I didn't have any issues when I used the 10.2 trim kernel.

if you have my chip you should be clear and should definitely do the upgrade to 10.2 and flash the trim kernel. However, remember that you do so at your own risk blah blah blah. (you should be all right) :silly: :silly:

You can also check the bug status of the various chips in the wiki page http://wiki.cyanogenmod.org/w/EMMC_Bugsmod

[Nook HD, HD+ Q&A, Help & Troubleshooting] Jann F:
I still use the TRIM Kernel with CM10.2 and had some random reboots (1 per week), but I don't think it has something to do with TRIM.

I'm not talking about random reboots. I'm talking about general performance. Audio from the jack is aweful, google search lags, some fc, general sporadic lag, battery life, some bugs.

That's strange...this has been the most stable ROM I've found for the HD+ and I haven't had any of the issues you described. Anyway, I believe TRIM is disabled in the 4.3 Carbon build.

Anyway I kinda need help, I funked up. This is not exactly on topic but I think this is a stupid problem. went to my nook Cwm recovery and factory resetted, formatted system cache and data, and when I selected install zip from sdcard the recovery couldn't find the sd anywhere. It was like sdcard/0, and then after this 0 directory there was another 0 directory similar to the other one, like every flash of new roms left its android skeleton structure and the new ones installed theirs inside that. In all of this I couldn't find the sd card with the new rom files that I just transferred via USB before doing the format. It's like it has a simulated sd card, and cannot read the real one.

I know that this has been debated before and the general consensus Is that we don't have support. I have seen though, some scrip mods to add support through modifying the kernel via twrp flashing for the nexus 4. Now the lgog and the n4 are very close as far as software, (yes I know that there are partition differences and other changes between the two) but can't the scripts be modified to work for us? Or is it easier to just do a n4 port and then run the scrips? If this has already been don't please link because I've searched and have come up empty.
